Sounds like you element was not receiving power. Often when the smoker is new, the connections are hard to seat properly. Try unplugging, and plugging in the power cords at each connection. Do this several times

If that doesn't work try testing the element by plugging the smoker cabinet directly in the wall socket. This should be only a test to verify that the element does work. You will need a computer or monitor power cord for this. If the element doesn't work open the generator and check for loose connections.
